If a sprinkler is color coded Red, what is its temperature rating?

Explanation:
Color coding on sprinklers is a quick way to show the temperature rating at which the head will release water. The higher the rating, the hotter the environment it’s designed to withstand before activating. Red is used for the highest rating, which corresponds to about 325–375°F (163–191°C). So a red-coded sprinkler is the high-temperature option, making 325–375°F the best match here. The other ranges represent lower temperature ratings and are indicated by different colors, not red. Remember, this rating is about when the sprinkler activates, not the water temperature.
